AUTOMOBILE-HORN.

Specification of Letters Patent.

Patented Nov. 3, 1914.

Application filed. March 23, 1914. Serial No. 826,723.

To all whom it may concern Be it known that 1, JOHN I'IENRY UrtroN,citizen of the United States, residing at Dunsmuir, in the county ofSiskiyou and State of California, have invented certain new and usefulImprovements in Automobile-Horns, of which the following is aspecification, reference being had to themcompanying drawings.

This invention relates to an improved automobile siren or horn and hasfor its primary object to provide a simple and eilicient device of thischaracter which is designed for connection with the exhaust of theengine, whereby the exhaust may be utilized for the operation of thedevice and cause the latter to emit a warning blast of sound.

More specifically stated, my invention has for a very important objectto provide a device of the above character embodying a tubular bodymember having a disk secured therein said disk being provided with aplurality of openings, and a rotatable member mounted uponone face ofsaid disk and pro vidcd with means whereby, in the passage of theexhaust through the openings in said disk, said member is rotated,whereby the same cooperates with the openings in the disk to produce thewarning sound.

The invention has for a further object to provide a siren or horn formotor vehicles,

which is very simple in its construction,

durable and reliable in practical use and may be easily and quicklyapplied to the exhaust of the engine or removed therefrom.

With the above and other objects in view as will become apparent as thedescription proceeds, the invention consists in certain constructions,combinations and arrangements of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in which- Figure 1 is aside elevation of an auto mobile siren, the bodythereof being partlybroken away; Fig.2 is a section taken on theline 2-2 of Fig. 1; Fig. 3is an enlarged detail elevation of the sound producing elements; Fig. 4is a face view of the rotatable disk.

Referring in detail to the drawing, 5 designates the horn body which isof tubular construction and preferably flared at one end. The oppositeend of this horn is provided with exterior screw threads to recelve aninteriorly threaded flange 6 upon the coupling member 7. This member isalso provided with interior threads upon its body portion for engagementwith the cxteriorly threaded end of an exhaust pipe, (not shown).

\Vithin the tubular body 5 of the horn, a metal disk 8 is arranged, saiddisk being provided upon its edge with laterally pro- JGCillIlg ears orlugs 9 adapted to be securely fastened to the wall of the horn 5 bymeans of belts or rivets 10. This disk is provided with a plurality oftapering openings 11, said openings gradually increasing in width fromthe central portion to the outer edge of the disk. This disk isfurtherprovided with a central circular opening to receive a bolt 12.

Upon the bolt 12, the rotatable disk.13 is engaged. This disk is alsoprovided with a plurality of substantially triangular shaped openings14, and preferably twice as many of these openings are provided as thenumber of openings 11 in the disk 8. This latter disk 13 is also formedwith a central opening for the accommodation of the bolt 12 and acylindrical boss 15 surrounds said opening. This boss is provided in itsend face with an annular race way to receive a series of bearing balls16. The end of the bolt 12 is provided with a collar 17 opposed to theboss 15 and also provided with a race way to receive said bearing balls.The other end of the bolt 12 is threaded to receive the nut 18 wherebysaid bolt is held in position and the rotary disk 13 retained in properrelation to the stationary disk 8.

It will be noted from reference to Fig. 4 that one of the edges of eachof the openings 14: extends tangentially from the periphery of the boss15. This edge of the opening as well as the outer curved edge whichextends in concentric relation to the periphery of the disk is providedwith a laterally extending flange or plate 19. These flanges areintegrally connected at the juncture of said edges of the opening.

In the use of my invention, the same is adapted to be connected to theexhaust pipe of a motor vehicle engine through the medium of thecoupling member 7. In the discharge of the exhaust, the same is directedagainst the disk 8 and passes through the openings 11 thereof. Thisexhaust i'm inging against the curved outer late or ange 19 on the disk14 rotates said disk. It will be noted that these plates or flanges areof tapering triangular form whereby, as they pass the openings 11 in thedisk 8, the passage of the exhaust through the gradually wideningopening will result in a loud noise which will be practically continuousowing to the arrangement of the openings in the rotating disk 13.

It will be seen from'this description that I have produced a very simpleand effective device whereby the exhaust of the motor vehicle engine maybe utilized for the purpose of producing a warning sound or noise andthereby operating to minimize the number of accidents occurring in theoperation ofsuch vehicles;

The several parts of my invention are of very simple form, and may beproduced at small manufacturing cost;

It will be apparent that the device can be made in various sizes and theopenings in the rotating and stationary disks may be of such size withrelation to each other that either a prolonged practically continuousnoise produced, or short intermittent blasts of noise, as may bepreferred; It will there fore be obvious that in putting the inventioninto practical use, I do not desire to be re stricted to the particularform and construc tion of the several elements employed but reserve theprivilege of resorting to all legitimate modifications thereof as may befairly embodied Within the spirit and scope of the invention as claimed.

Having thus described the invention, What is' claimed is:

A device of the character described coinprising a tubularbody and meansfor c0nnecting the same at one end to the exhaust of an englne, astationary disk secured Within said body and having a plurality ofradially disposed tapering openings therein, a second disk rotatablymounted upon one face of the stationary disk, said latter disk alsobeing provided with a plurality of triangular shaped openings, the outeredges of which are disposed in concentric relation to the edge of thedisk, and integrally connected triangular shaped blades projectinglaterally from the outer edge and one of the other edges of each of saidtriangular 0penings, substantially as and for the purpose specified.

In testimony whereof I hereunto afiiX my signature in the presence oftwo witnesses, JOHN HENRY UPTON.
